It seems that English food manufacturers are cutting more than corners when selling 'budget priced' products... From the London Times:
Yuk - the sausage rolls with just 6% pork
Big supermarkets' budget food is selling well but its quality is poor
Some of Britain's biggest supermarket chains are compromising on quality by selling budget items such as sausage rolls with as little as 6% pork.
Sainsbury's and Tesco are working hard to market their low-cost lines as they compete with discount chains to attract cash-strapped shoppers.
This is often coming at the expense of quality, however. An analysis of low-cost foods at the two chains has found, in addition to the sausage rolls, fisherman's pies with 9% fish and square cheese slices with 11% cheese. The products have been bulked out with ingredients such as water, animal fat and sugar.
The items help the supermarkets to undercut bargain-basement stores such as Aldi and Lidl, which have posed a growing threat as middle-class families seek to economise.
The article goes on to note that some other companies are actually delivering a lot better product for the money. Pays to read the labels...
